sweatshirt
The sweatshirt (English sweat = to sweat, shirt = shirt) was originally the name for a sports pullover . Sometimes sweatshirts are the tops of jogging suits . Sweatshirts with hood are also Hoodie called or sweatshirt.
Specialty
The fabric of a sweatshirt consists of a special knit fabric. This is knitted on a single surface on circular knitting machines (right / left fabric). A special lining thread is carried on the back, which is twisted softer than the basic knitting thread that is visible on the front. This is roughened during the finishing process , which leads to the typical fluffy inside of the sweatshirt fabric. For this reason, this substance is also called "feed" in specialist circles.
advantages
The basic threads of the sweatshirt fabric are no thicker than those of a T-shirt , but the large lining thread makes the goods thicker and warms up. Since this fabric can be manufactured on high-performance machines and is normally made up, it is cheaper to produce than, for example, a coarse knit sweater.
disadvantage
The fiber of the lining thread is damaged by the mechanical stress of the shearing process, for this reason the fluffy inside becomes knotty and hard after prolonged use, as the fibers continue to break. Thus, the warming function of the garment also decreases over time.
